To all whom "it may concern:

Be it known that I, Eonnnr H. GOLD, a citizen of the Uni-ted States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Heating Systems, of which the following is a specification.

My invention relates to steam heating systems and has for its object to provide means for ridding the radiating pipes of such systems of their water of condensation at certain desired points.

The invention is designed to obviate certain defects particularly in railway car heating systems, which defects arise because of the accumulation of water of condensation. For example, when the train is one grade for some time the water of condensation in the steam-coils tends to collect in the lower ends of the coils, hindering the circulation of steam and consequently the proper heating of the car. Also in some well known arrangements thehcating pipes are divided into a number of coils placed along the sides of the car and joined at the bottom. The

water of condensation collects in the connecting pipes and consequently each of the coils under ordinary conditions has to have its particular inlet and its particular controlling means in case the system is an automatically regulated one.

By my invention the system of radiating pipes may be l'rccd of water at the low points without permitting the escape of steam and so as to allow automatic control of all the coils as a .unit. These embodiments are typical and illustrative merely. The invention may be embodied in railway car heating systems dii'ierent from those shown or in other heating systems where similar conditions prevail.

The invention is illustrated in the accom panying drawings, in which Figure 1. is a diagrammatic view of a form of heating system with the devices of my invention applied thereto. Fig. 2 is a similar view showing a difierent arrangement of radiatingcoils. Fig. 3 is an enlarged sectional view of the controller shown in Fig. 1. Fig. 4 is a vertical section through one form of relief l'itting. Figs. 5 and 6 are section on lines 55 and (5(5,.respectively, of Fig. d, looking in the direction of the arrows. Fig. 7 is a vertical section through a modified form of fitting. Figs. 8 and 9 are sections on :lines 8-8 and 9-9, respectively, of F .7 Fig. 10 is a vertical section through another modification, and Fig. 11 illustrates the arrangement of the heating coils" of Fig t in a railway car, the latter being indicated by dotted lines.

Like characters of reference indicate the same parts ,'-in the several figures of the drawings. f

Referring first to Fig. l, A. represents a coil of pipe I; an automatic controller, .0 a supply pipe from the train pipeto the. controller, D a pipe from the controller to the coil, E a return pipe to the controller, and F, F reliei fittings, such as are shown in detail in Figs. lto (S or 7 to 9.

The controller chosen for purposes of illustration is shown in Fig. 3, and is a well known device, by means of which the steam at the outlet of the radiating coil controls the admission of steam to the coil.

Referring to F jg. 3, 11 is a casing to which is connected a drip pipe 12 and which has the partition the latter, with another partition 14, forming an admission chamber 15 to which pipe 0 leads, and a valve chamber 16, from which leads the pipe 1). These chambers are connected by a port controlled by valve 1'? provided witha stem 18, to which is connected a lever 15) pivoted to the casing and engaging a rod 90 extending down the drip pipe to a thermostat 21 at the lower end. This thermostat may be of any desired term. 1 have shown a sack, partially filled with an easily volatilizable liquid, of ordinary construction. Pipe E leads into the drip 12.

The coil A may be of any desired arrangement. I have shown pipe D leading to a header 22 from which lead pipes 23, 24 on one side and pipes 25, 26 on the other-to respectively connecting pipes 27 and 28 which are connected also by pipe 29 from which leads return pipe E. The coil A mayextend the length of the car and the pipes forming it may, of course be multiplied to any extent.

lit the ends of coil A, I place relief fittings F, F. Figs. t to 6 show one form of such fitting, in which 30- is a casing having outlet and inlet ports 31 and 32 and water discharge port 33 and on the interior a partition 31 extending in front of the water discharge port and into a pocket, 35 formed on the lower end of the fitting, but so as to beyond said portion on the lower level ating pipes open to the atmosphere, consisting of a eontinuons steam conduit, of which one portion isnt a lower ievei than the next succeeding portion, of a relief fiiiiing lorated in the portion at the low level, provided with a water outlet which is sealed ngziinsi the escape of steam but continuously open to the atmosphere for the escape of Waier of condensation. and a controller for coni'rolline; the inflow of steznn to said system of 1m iating pipes, con'iprieing :1 thermostat under influence of the steam in said. eondnit- 5.Tl1e combination with a 'rziili'ny car, of
